Description

Technical Field

[0001] The utility model relates to the field of motor-related products, in particular to a high-efficiency three-phase asynchronous motor. Background Art

[0002] The three-phase asynchronous motor is a type of induction motor, which is powered by 380V three-phase AC current. Since the rotor and stator rotating magnetic field of the three-phase asynchronous motor rotate in the same direction and at different speeds, there is a slip rate, so it is called a three-phase asynchronous motor. The speed of the rotor of the three-phase asynchronous motor is lower than the speed of the rotating magnetic field. The rotor winding generates electromotive force and current due to the relative motion between the rotor winding and the magnetic field, and interacts with the magnetic field to generate electromagnetic torque to achieve energy conversion. Compared with the single-phase asynchronous motor, the three-phase asynchronous motor has good operating performance and can save various materials;

[0003] Since the rotor and stator inside the motor are under high temperature for a long time, maintenance is often required. It is cumbersome for the staff to disassemble the motor casing. Most of the existing motor casings are one-piece structures. The motor casing is welded, which is not convenient for maintenance. When flanges are used for installation, it takes a lot of time for the staff to repeatedly disassemble and assemble the flange, which is defective. Utility Model Content
